Publication number: 20240023989Abstract: Adjustable-length surgical access devices are disclosed herein, which can advantageously allow an overall length of the access device to be quickly and easily changed by the user. The access devices herein can reduce or eliminate the need to maintain an inventory of many different length access devices. In some embodiments, the length of the access device can be adjusted while the access device is inserted into the patient. This can reduce or eliminate the need to swap in and out several different access devices before arriving at an optimal length access device. This can also reduce or eliminate the need to change the access device that is inserted into a patient as the depth at which a surgical step is performed changes over the course of a procedure. Rather, the length of the access device can be adjusted in situ and on-the-fly as needed or desired to accommodate different surgical depths.Type: ApplicationFiled: September 30, 2023Publication date: January 25, 2024Inventors: Michael White, Joern Richter, Jan Klett, Stephane Gully, Veronique Zollmann, Richard Kocharian

Publication number: 20240023988Abstract: Surgical access port stabilization systems and methods are described herein. Such systems and methods can be employed to provide ipsilateral stabilization of a surgical access port, e.g., during spinal surgeries. In one embodiment, a surgical system can include an access port configured for percutaneous insertion into a patient to define a channel to a surgical site and an anchor configured for insertion into the patient's bone. Further, the access port can be coupled to the anchor such that a longitudinal axis of the access port and a longitudinal axis of the anchor are non-coaxial. With such a system, a surgeon or other user can access a surgical site through the access port without the need for external or other stabilization of the access port, but can instead position the access port relative to an anchor already placed in the patient's body.Type: ApplicationFiled: September 30, 2023Publication date: January 25, 2024Inventors: Michael White, Stephane Gully, Jan Klett, Peter Senn, Joern Richter

Patent number: 11813026Abstract: Systems, devices, and methods are provided for trajectory guidance using instrument position data and planned trajectories into or through a patient's body or an object. Lasers are emitted from a laser system toward the patient's body or object at an area within or proximate to the instrument operator's line of sight. Information about the instrument, including the position of its proximal and distal ends, and the position of the patient's body or object, are used to direct the emission of the lasers in real-time during operation of the instrument. The emitted lasers function as visual cues indicating the manner in which to position the distal and proximal ends of the instrument to properly align with the planned trajectory. A guidance map on the instrument can be used to output visual cues about the position of the distal and proximal ends of the instrument relative to a planned trajectory.Type: GrantFiled: April 5, 2019Date of Patent: November 14, 2023Assignee: Medos International SarlInventors: Joern Richter, Marc Puls, Thomas Gamache
